### Question: How does desmoid tumor form?
### Response: Scientists are always working to understand how tumors form, but it can be hard to prove We know that some people with a family history of desmoid tumor s have a change in a gene called adenomatous polyposis coli, or APC This change causes too much of a protein called beta-catenin in parts of your cells Too much beta-catenin can cause cells to grow when they shouldn’t In some desmoid tumor s, there is too much beta-catenin, even though APC is normal APC and beta-catenin are important in many common cancers, such as colon cancer, and scientists are trying to use this information to develop better cancer treatments, which will help people with desmoid tumor s
